Genetic architecture is the underlying genetic basis of a phenotypic trait and its variational properties. [1] Phenotypic variation for quantitative traits is, at the most basic level, the result of the segregation of alleles at quantitative trait loci (QTL) . [ 2 ]
A guerrilla foco is a small cadre of revolutionaries operating in a nation's countryside. This guerrilla organization was popularized by Che Guevara in his book Guerrilla Warfare, which was based on his experiences in the Cuban Revolution. Guevara would go on to argue that a foco was politically necessary for the success of a socialist revolution.
In the "Spandrels" paper, Gould and Lewontin argue that the mosaic design on the spandrels in St. Mark's Basilica is "so elaborate, harmonious, and purposeful that we are tempted to view it as the starting point of any analysis, as the cause in some sense of the surrounding architecture." They then claim that this would be inappropriate ...
As a whole, these models argue the inadequacy of the modern evolutionary synthesis on the roles of genes and natural selection as the principal explanation of living structures. Developmental systems theory embraces a large range of positions that expand biological explanations of organismal development and hold modern evolutionary theory as a ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time. The role of genes in pattern formation is an aspect of morphogenesis, the creation of diverse anatomies from similar genes, now being explored in the science of evolutionary developmental biology or evo-devo.
The word archetype, "original pattern from which copies are made," first entered into English usage in the 1540s. [2] It derives from the Latin noun archetypum, latinization of the Greek noun ἀρχέτυπον (archétypon), whose adjective form is ἀρχέτυπος (archétypos), which means "first-molded", [3] which is a compound of ἀρχή archḗ, "beginning, origin", [4] and ...
Cognitive biology is an emerging science that regards natural cognition as a biological function. [1] It is based on the theoretical assumption that every organism—whether a single cell or multicellular—is continually engaged in systematic acts of cognition coupled with intentional behaviors, i.e., a sensory-motor coupling.
